When I save an rtf file in text edit, it retrieves with codes

Question

Every time I save an RTF file since lion, when I later retrieve a file it's code filled file. Does anyone know what this is and how to prevent it (or tell text edit to retrieve normally)?
example from a recent file:
{\rtf1\ansi\ansicpg1252\cocoartf1138\cocoasubrtf510
{\fonttbl\f0\fswiss\fcharset0 Helvetica;\f1\fswiss\fcharset0 ArialMT;}
{\colortbl;\red255\green255\blue255;\red26\green26\blue26;}

I resolved this by using the open... menu and unchecking "Ignore Rich Text Commands"
